chemicals known to the State of California to cause

cancer, birth defects or other reproductive harm.

Some examples of these chemicals are:

• Lead from lead-based paints.

•Crystalline silica from bricks, cement, and

other masonry products.

• Arsenic and chromium from chemically

treated lumber.

Your risk from these exposures varies, depending on

how often you do this type of work. To reduce your

exposure to these chemicals: work in a well ventilated

area, and work with approved safety equipment, such

as those dust masks that are specially designed to fil-

ter out microscopic particles.

OPERATION

Installing Bits

The Model H3117 can use most bits and

cutters that have a 1⁄8" diameter shaft. See

the Grizzly catalog or website for a com-

plete listing of available bits and acces-

sories.

To install a bit:

1. Unplug the tool from the power

source!

2. Depress the Collet Lock. The Collet

Lock is a small black button near the ip

of the Grinder. Initially the Collet Lock

may not depress when pushed; how-

ever, continue to apply and hold pres-

sure on the Collet Lock.

3. While applying pressure to the Collet

Lock, use your other hand to rotate the

Collet Nut and loosen it. At some point

through the rotation the Collet Lock will

engage, preventing further rotation of

the Collet Nut.

4. With the Collet Lock engaged, the

Collet Nut should easily loosen and

unthread by hand. DO NOT complete-

ly remove the Collet Nut from the shaft.

5. Insert the end of a bit into the Collet. At

least 1⁄2" of the bit shaft should be

mounted into the end of the Collet.

6. While depressing the Collet Lock,

rotate the Collet Nut to secure the bit.

Only hand tighten the bit. Excessive

tightening with the Collet Wrench is not

necessary.

Before Start Up

1. Be sure the bit and the Collet Nut are

secure on the grinder shaft.

2. Wear safety glasses and a dust mask

when operating the grinder.

3. Turn the Power Switch to the OFF “—”

position.

4. Plug the grinder into the power source.

DO NOT use bits or cutters with a

cutting surface larger than 1" in

diameter. The bit could break apart

under the stresses of high speed use

causing serious personal injury.

About Your New Grinder

The Grizzly Model H3117 is a variable

speed, rotary-style tool capable of speeds

from 0-30,000 RPM. It is capable of a wide

range of grinding, cutting, polishing,

drilling, engraving, and cut-off operations.

Please take the time to become familiar

with this instruction manual. The informa-

tion contained will allow you to get the

maximum enjoyment and use from your

new tool.

H3117 Mini Grinder -5-

High RPM Uses

Higher RPM settings are best for general

carving, cutting, routing, and grinding. The

grinder will perform more work at faster

RPM settings.

Low RPM Uses

Lower RPM settings are best for grinding

and cutting materials that have low melting

points. Plastics in particular will often melt

from the extreme heat generated by high

speed bits.

Low RPM settings are also ideal for polish-

ing and buffing with the felt accessories

included.

Use low RPM settings when working

with plastics or other materials with

low melting points. Melted plastics

can liquefy, be thrown into the air,

and stick to the operator, causing

serious personal injury.

The Model H3117 is best suited for high

RPM, low torque applications. Most opera-

tions performed with the grinder will per-

form best at the higher RPM settings; how-

ever, slower RPM settings are ideal when

working with plastics that melt easily.

Always test the bit and RPM combination

on a scrap piece of material similar to the

workpiece. Trial and error is the best way

to determine the ideal setup.

To use the grinder:

1. Grasp the grinder with a secure grip.

2. Turn the Power Switch to the ON “O”

position.

3. Adjust the Speed Dial to change the

RPM. “1” is the lowest RPM and “Max”

is the highest RPM. The best speed for

each job can vary.

Using The Grinder

Failure to wear safety glasses while

operating the grinder could cause

serious personal eye injury.

to clean the tool could explode caus-

ing serious personal injury. DO NOT

nance!

Carbon Brushes

The Model H3117 has a brush-type electric

motor. Periodically remove and inspect the

2 carbon brushes under the Brush Covers.

clean the grinder with compressed air. DO

NOT use flammable products to clean the

grinder.
